Getting Promoted

Thursday, March 26, 2015

What do Larry Summers, Doug Elmendorf, and Greg Mankiw have in common?

Only one of us won a John Bates Clark Medal. Only one of us became Director of the Congressional Budget Office. Only one of us wrote a best-selling textbook.

But all three of us were ec 10 section leaders early in our careers.

Being an ec 10 section leader is one of the best teaching jobs at Harvard. You can revisit the principles of economics, mentor some of the world’s best undergraduates, and hone your speaking skills. In your section, you might even have the next Andrei Shleifer or Ben Bernanke (two well-known ec 10 alums). And believe it or not, we even pay you for this!

If you are a graduate student at Harvard or another Boston-area university and have a strong background in economics, I hope you will consider becoming a section leader in ec 10 next year. Applications are encouraged from PhD students, law students, and master's students in business and public policy.

If you think you might be interested, please come to one of the information sessions we are holding:

Monday, March 30th at 6 p.m. in Aldrich 109 at the Harvard Business School

Thursday, April 2nd at 6 p.m. in the 3rd floor Littauer lounge of the Harvard Economics Department

Monday, April 6th at 6
p.m. in Taubman 401 at the the Harvard Kennedy School of Government

The book is a few years old, but I had not heard of it. It gives readers a lens into the field of moral psychology, together with dashes of philosophy, anthropology, behavioral genetics, political science, and even some behavioral economics.

International trade is fundamentally good for the U.S.
economy, beneficial to American families over time, and consonant with our
domestic priorities. That is why we support the renewal of Trade Promotion Authority
(TPA) to make it possible for the United States to reach international agreements
with our economic partners in Asia through the Trans-Pacific Partnership (TPP) and
in Europe through the Transatlantic Trade and Investment Partnership (TTIP). Trade
Promotion Authority provides for an up or down vote on these agreements,
without amendments, and thereby encourages our trade partners to put their best
offers on the table.

Expanded trade through these agreements will contribute to
higher incomes and stronger productivity growth over time in both the United
States and other countries.U.S.
businesses will enjoy improved access to overseas markets, while the greater
variety of choices and lower prices trade brings will allow household budgets to
go further to the benefit of American families.

Trade is beneficial for our society as a whole, but the
benefits are unevenly distributed and some people are negatively affected by
increased global competition.The
economy-wide benefits resulting from increased trade provide resources to make
progress on important social goals, including helping those who are adversely
affected.

Increased global economic engagement will enhance U.S.
global leadership in line with our values. Indeed, trade agreements signed under
both Democratic and Republican Presidents have included provisions to combat
corruption and to strengthen environment and labor standards.

It is not desirable for trade agreements to include
provisions aimed at so-called currency manipulation. This is because monetary
policy affects the value of currencies.Attempts
to penalize countries for supposedly manipulating exchange rates would thus
impose constraints on U.S. monetary policy, to the detriment of all Americans.

We believe that agreements to foster greater international
trade are in our national economic and security interests, and support a
renewal of Trade Promotion Authority.

No Way to Avoid It

[A]ccurate dynamic scoring requires more information than congressional proposals typically provide. For example, if a member of Congress proposes a tax cut, a key issue in estimating its effect is how future Congresses will respond to the reduced revenue.

This raises important questions for which we have no easy answers. In the coming years, will these Congresses respond quickly to the revenue shortfall, or will they let budget deficits fester? When they act to close the budget gap, will they increase taxes, or will they cut spending? If they cut spending, will it be on consumption items, such as health care for the elderly, or on growth-promoting investments, such as education for the young? The impact of the initial tax cut depends crucially on the answers to these questions, but budget analysts usually have little to go on but speculation.

Greg also opined on the second round effects, how policy might change economic
outcomes which might change future policy. Here I'll go with the old fashioned
approach -- let's not go there!

I understand the desire not to go there. The problem is, you cannot avoid going there.

Dynamic scoring requires the solution of a general equilibrium model. To solve a dynamic GE model, you need to specify how the government is going to satisfy its present-value budget constraint. You might be tempted to ask the model what happens if the government cuts taxes and never does anything else. But you won't get very far. The model will tell you that the government has to do something else eventually, and it won't tell you what will happen if the government tries to do something impossible.

About Me

I am the Robert M. Beren Professor of Economics at Harvard University, where I teach introductory economics (ec 10). I use this blog to keep in touch with my current and former students. Teachers and students at other schools, as well as others interested in economic issues, are welcome to use this resource.
